Norton 66254428456 Aluminum Oxide Deburring Wheel

Product Description

The NORTON 66254428456 is a unitized aluminum oxide deburring wheel designed for edge deburring, blending, and light surface finishing on metal workpieces. At 2 inches in diameter with a 1/4 inch face width and a 1/4 inch center hole, this compact wheel mounts directly to small-bore rotary tools without adapters. The density 3 medium-grade construction balances conformability with cut rate, making it suitable for removing sharp burrs and light scale from ferrous and non-ferrous metals. It is a standard choice for machinists, fabricators, and maintenance technicians who need controlled, repeatable results on smaller workpieces and internal passages.

This deburring wheel is used in light fabrication, machine shop finishing, and maintenance applications where a bench grinder or large wheel is impractical. The 1/4 inch arbor fits directly into die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders, making it versatile across common shop and field setups. It is well suited to deburring drilled holes, chamfering edges, and blending weld toes on small parts in both production and repair environments.

Key Features

• Aluminum oxide abrasive material provides consistent cut on ferrous metals and general-purpose applications
• Density 3 medium-grade unitized construction conforms to contours while maintaining abrasive action
• 2 inch diameter and 1/4 inch face width sized for detail work and restricted-access areas
• 1/4 inch center hole fits standard die grinder and rotary tool collets with no adapter required
• Compatible with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders
• Lightweight at 0.0146 pounds, minimizing tool fatigue during extended deburring work

Compatibility

Designed for use with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders equipped with a 1/4 inch collet or chuck.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard rotary tool equipment. Ensure the grinder is powered off and disconnected from its air or electrical supply before mounting or removing the wheel. Thread or seat the wheel onto the 1/4 inch arbor securely before operating, and verify the tool RPM rating does not exceed the wheel's rated maximum speed. Wear appropriate eye protection and follow applicable ANSI grinding safety standards during use.
